A questionnaire survey was conducted on 426 employees of high-tech enterprises within Jiangsu Province. Multiple regression method was used to test the hypothesis based on the questionnaire reliability and validity analysis. The results show that the four dimensions of CSR including employees responsibility, products responsibility, environment responsibility and charitable responsibility have positive effect on the affective commitment;while the continuance commitment might be more influenced by the environment and charitable responsibility. The regulatory focus plays a moderate effect between CSR and EOC. Promote regulatory focus have positive impact on affective commitment and negative impact on continuance commitment. Defense regulatory focus is just on the opposite.展开更多

The essential roles of innate immunity in cerebral ischemia are increasingly identified, but no studies concerning the influence of brazilein on the innate immunity receptors have been reported. The present study was designed to investigate the regulation of NOD2 （Nucleotide-binding oligomerization domain-containing protein 2） by brazilein for its protection of neuron in cerebral ischemia in vivo and oxygen-glucose deprivation in vitro. The results showed that brazilein could reverse the elevated expression of NOD2 and TNFa （tumor necrosis factor alpha） elicited by cerebral ischemia and reperfusion. This reduction could also be detected in normal mice and C 17.2 cells, indicating that this suppressive effect of brazilein was correlated with NOD2. The results from GFP reporter plasmid assay suggested brazilein inhibited NOD2 gene transcription. In conclusion, brazilein could attenuate NOD2 and TNFα expression in cerebral ischemia and NOD2 may be one possible target of brazilein for its immune suppressive effect in neuro-inflammation.展开更多
